Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fixing tapes used in tape recorders, VTR cassettes, etc. with clamps.

More specifically, the present invention relates to a method of fixing a tape wound on a plastic reel with a plastic clamp. 3. A commonly used method for fixing tape is to wrap one tape A as shown in Fig. 2 around a plastic reel shaped as shown in Fig. 1, and then wrap it around a plastic reel shaped as shown in Fig. As shown in FIG. 4, the tape A is pressed onto the reel R by a clamp C made by a steel company, and the tape is fixed between the clamp and the reel.

In this case, as shown in Fig. 3, the clamp has protrusions 5, 6 with claws 3, 4 on both sides, and when the clamp is fitted into the reel, the clamp claws 3, 4bS reel retaining portions 1 and 2, it is fixed so that it will not come off. However, this conventional method has the disadvantage that the fixed tape tends to come off easily.

That is, after the tape is fixed as shown in FIG. 4, when a tension force bS is applied to pull the tape outward as indicated by the arrow in FIG. 4, the clamp C comes off from the reel R and the tape A is easily removed. This is because when the tape is pulled outward, the protrusions on both sides of the clamp are bent inward, so claws 3, 4b5
This is because the reel comes off from the retaining parts 1 and 2 of the reel. Further, when the tape is pulled outward, a force that lifts the clamp is also applied, so that the clamp is easily separated from the reel, and the tape hS is dislodged. The present invention changes the structure of the clamp and reel to prevent the tape b3 from coming off.

That is, according to the present invention, there is an advantage that the tape bS cannot be removed even if a force bS is applied to pull the tape outward after the tape is fixed with a clamp. The method of the invention will be explained below with reference to the drawings.

FIG. 5 shows the shape of a plastic lamp according to the invention. That is, the present invention uses an "E"-shaped clamp that has protrusions 1 and 8 on both sides and also has a protrusion 9 in the center.
The protrusions T and 8 on both sides have two claws 10 and 11, respectively.
and 12 and 13, and are designed to prevent it from coming off when it is fitted into the reel. Next, the shape of the reel R fitted with this clamp C is shown in FIG.

That is, in the present invention, the claws 10 and 13 on both sides of the clamp C
These claws 10,
13 and corresponding retainers 14 and 11, respectively, and two protrusions 18 and 19 provided on the inside of the reel to fix the claws 11 and 12 provided on the inside of the protrusions 7 and 8 of the clamp.
The retainers 15 corresponding to these pawls 11 and 12 respectively
, 16 are provided. The convex portion 9 at the center inside the clamp is provided so as to fit between the convex portions 18 and 19 of the reel. In the present invention, the spear force used to fix the tape is similar to the conventional force method.

That is, after winding the tape A around the reel R, the clamp C is fitted onto the reel R to fix the tape between the clamp and the reel. FIG. 7 shows the state in which the tape A is fixed. That is, the clamp pawls 10,1
1, 12 and 13 are reel retaining parts 14 and 1, respectively.
5, 16, and 17, and is fixed. In addition, the protrusion 9 at the center of the inside of the clamp is connected to the 2
It fits between the tips of the convex portions 18 and 19 of . When the tape Ab5 is fixed with such a fitting according to the method of the present invention, after fixing, the tape A is pulled outward (in the force direction of the arrow) along the outer periphery of the reel, thereby pushing the clamp inward. Even if force B3 is applied, the clamp deforms B5 convex portions 18, 9, 1
9, the clamp t)3 cannot be dislodged. Therefore, the force method of the present invention is far superior to the conventional force method for fixing the tape with a clamp, and has the advantage of reliably preventing accidents during use.

Claims (1)

[Claims] 1 In a method of wrapping tape around a plastic reel and fixing the tape with a clamp, it has a protrusion on both sides, a protrusion in the center, and two protrusions on each side to prevent it from coming off. It has an E-shaped clamp on both sides, and the outer periphery has two retainers that correspond to the claws on both sides of the clamp, and the inner periphery has claws provided inside the protrusions on both sides of the clamp. Using a reel with two protrusions each having a corresponding retainer so that the protrusion on the inside center of the clamp fits between the tips of the two protrusions provided on the inside of the reel, the tape is rolled in one piece. A method of fixing a tape with a clamp, which is characterized in that the tape is wound and then fixed between a reel and a clamp.
